A chip based on microelectrode arrays for the fabrication of single nanowire systems via dielectrophoresis effect

Original language description

We present an assembling method to integrate nanowires with prepatterned electrode via dielectrophoresis (DEP) effect. The proposed topology of test electrode system was designed to understand the different factor involved in the dielectrophoresis process and determine the optimal conditions for a facile integration of semiconducting metal oxide based nanowires produced via aerosol-assisted chemical vapor deposition. [1] Tests of the separation of the nanowires from the basic substrate via sonication revealed nanowires with lengths above 5 µm and the widths above 100 nm. The microarray test chips for dielectrophoresis were designed based on this geometrical features. Results obtained from SEM, optical microscopy and electrical measurement was examined. Further strategies and design improvement are suggested and analyzed for gas sensing application.
